As of Ubuntu 10.04, Ubuntu had 28 fully translated languages and a total of 218 supported languages.

You may have more luck digging into the Ubuntu translation pages. I haven't been able to find an update on the data provided in the first link.

It looks like you can get a raw export of the translation coverage on 12.10(Quantal)here along with some instructions on the Ubuntu Translations Statistics page. There is a web app to present/interpret the data, but I have not used it.
